I agree, Rob. If EV battery chemistries are going to come remotely close to what gasoline already gives us, this is the way it will happen. The people I spoke to said we have to be ready to move beyond lithium-ion, and the ARPA-e program is a great way to start doing that.
Good point, Dennis. I drive a car with 175,000 miles on it and I believe it's got at least another 75,000 left. My son drives a car with 190,000 miles on it. Average vehicle life has soared over the last 20 years. Regarding high volume EVs: You hit it on the head. The key lies in your use of the words "high volume." Pure EVs are great, fun vehicles to drive, but the average consumer can't afford a second car that costs $30,000 to $40,000. Until higher energy batteries are readily available and until cost drops, pure EVs will see low volumes.
I agree, Chuck. The lithium-ion battery seems to have hit a wall. But who knows. In the time it takes for a battery based on alternative chemestry becomes feasible, the lithium-ion battery may have sacled its wall.
Charles, I agree completely with you on this point. I'm driving a Toyota Pre-Runner and I cannot justify an EV at $40k as a replacement. I have a 74 mile round-trip commute every day to one client. Right now, until the industry can generate more miles between charges and bring down the purchase price, an EV is just not in my future.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
